Hi

Can you verify the HttpService is available at all in the framework ? (You =
might try to access the web console)

If not, you might have an issue to not properly setup the Http Service brid=
ge: This requires wiring from the servlet which is actually deployed in the=
 servlet container. See [1] and the linked examples for details.

Regards
Felix
